wmoivntt- SPECIFICATION forming part of Letters Patent No. 272,226, dated February 13, 1883.

Application filed December 12, 1882.

Toall whom it may concern Be it known that I, CHARLES M. FORD, of Bellevue, in the county of Huronand State of Ohio,haveinvented a new and useful Improvement in Devices for Converting Rotary into Reciprocating Motion, of which the following is a full, clear, and exact description.

My invention relates to devices for converting rotary into reciprocating motion, and is applicable to windmills employed for working lift-pumps or other devices by means of avertically-reciprocating connecting-rod; and it cousistsof an improved arrangementof spring counterbalance attachment for effecting uniformity of the action of the mill, all as hereinafter fully described;

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a sectional elevation of the tower of a windmill, showin g the application of my improved counterbalancing attachment to the connecting-rod.

I propose to apply a couple of springs, a, of any'approved form or construction,substantially such as represented in the drawing to the connecting-rod b, by connecting them to opposite sides of said rod, and fastening them to the cross-piece cof the tower in such a manner that said springs will be subjected to the requisite stress on the downstroke of the connecting-rod to resist the tendency of the gravity of the rod to give undue impetus in that direction, and to lift on the return-stroke an amount equal to the resistance of the gravity on the upstroke, thus effecting uniformity of action, whereby the mill will run steady and with much less wear, besides being able to work in lighterwinds than it otherwise could.

(No model.)

.to set the connections so that the stress will begin when the rod has moved about half its downstroke; but the point where the stress should begin will vary with different conditions.

A-single spring attached to one side of the connecting-rod would serve very well, except for the side draft it would make. I therefore propose to employ two for balancing the side draft of each by the other.

Having thus described myinventiou,what I claim as new, and desire to secure by Letters Patent, isy 1. The combination of a pair of counterbalancing springs, a, with the vertically-reciprocating connecting-rod, said springs being attached to cross-piece 0 and connectedto said rod, substantially as described.

2. The combination of a pair of counter balancing-springs, a, links cl, and hooks 6 with the vertically-reciprocating connectingrod b, substantially as described.

3. The conlbinatipn' of a pair of counterbalancing-springs, a, links (1, and hooks c with the vertically-reciprocating connecting-rod b, said hooks being adjustable on said rod, substantially as described.
